Yes. Nor is a predisposition an excuse for a homosexual.
Some people have particular sinful predispositions like lying, cheating, stealing, and...sexual perversions including homosexuality.
We were created with free will to overcome our sinful predispositions. To say that we are slaves to our predispositions is to say that we are not men but animals.
They that deny a God destroy man's nobility; for certainly man's of kin to the beasts by his body; and if he be not of kin to God by his spirit; he is a base and ignoble creature.
Sir Francis Bacon, Of Atheism
“We were created with free will to overcome our sinful predispositions. To say that we are slaves to our predispositions is to say that we are not men but animals.”
That’s exactly what today’s secular left(Democrats and Republicans alike) believes about our species, i.e., that we are no better than animals.
